18 Claims.

This invention relates to polishing means more particularly for waxing and polishing floors and the like in domestic establishments for example.

The invention aims to provide a relatively light weight, portable machine for this purpose which simultaneously deposits the wax upon the floor and rapidly rubs it in, advantageously by a reciprocating or oscillating motion, which simulates hand rubbing while substituting the rapidity and uniformity of a relatively short stroke of operation for the customary pressure and length of stroke of conventional hand waxing.

It is well known that householders are becoming accustomed to and increasingly demanding light weight portable appliances, electrically operated, for performing a constantly greater number of tasks about the home, to relieve the time and drudgery of manual work. The care of wood floors with their inherently attractive appearance when waxed and polished, is a field which has been somewhat neglected and the demand for a portable electric waxing and polishin machine has heretofore not been met.

The machine of the present invention provides a remarkably simple and inexpensive device for this purpose which may be produced in quantities at low cost and which may be stored ready for instant use and handled by the housewife or householder in much the same way as the usual family vacuum cleaner for instance.

These and other objects and advantages will be apparent from the following description, taken together with the accompanying drawings, of illustrative structures embodying the invention, and in which drawings- Figure 1 is a plan view of one form of the device with parts broken away for purposes of description;

Figure 2 is a longitudinal vertical sectional view taken on the staggered line 2-2 of Figure 1;

Figure 3 is a partial sectional view similar to Figure 2 but showing in addition a modification of the invention and being a section taken on the staggered line 3-3 of Figure 4;

Figure 4 is a bottom view of the structure shown in Figure 3; and

Figure 5 is a-reduced general view of the machine, somewhat schematic.

Referring in detail to the illustrative construction shown in the drawings, the frame I0. is housing-like and somewhat similar in size and appearance to the casings or housings of domestic floor machines of various kinds. It may advantageously be constructed of amaterial such as aluminum or a substitute therefor, combining lightness with strength. The frame is, in general, divided into two compartments II and I2, the compartment II being what may be called the housing for the appliance parts of the device and the compartment I2 the housing for the mechanism for operating the appliance parts and for mobilizing the machine.

The compartment I2 is advantageously somewhat triangular in a horizontal plane, and mobilizing means are here represented by a pair of rubber-tired wheels I3 axled as at I4 in opposite longitudinal sides of the frame and a single similar wheel I5 axled as at I6 in a swiveling foot I! at the tapered rear end of the device. The foot I! may be of the well-known anti-friction caster type for easy swiveling purposes with a roller plate bearing I8, and the upper part I9 of which foot may be retained in a suitable socket portion 20 of the frame by a set-screw 2I. The mechanism compartment I2 of 'the frame is desirably elevated somewhat above the floor 22, upon which the machine is intended to operate, by the wheels I3 and I5, but the appliance compartment II desirably projects nearer the door and terminates in a band 23 of sponge rubber or the like which extends downwardly into contact with the floor and thus bounding the appliance compartment at this point to act. somewhat as a suction cup for the appliance compartment and also to provide a buffer which will guard against scratching of furniture or other Woodwork by the metal parts of the machine when in operation, the band 23 being arranged to project outwardly beyond the perimeter of the appliance compartment, this compartment at the same time being of a greater dimension transversely of the machine than the mechanism compartment [2.

Following more particularly the present invention and turning first to Figures 1 and 2, the appliance compartment II is formed at its upper end somewhat as a hopper-like reservoir 24 which is bottomed by a pair of relatively movable overlapping apertured plates 25 and 26. thus providing a sifter for a comminuted polishing material such as powdered wax which may be deposited in the reservoir 24 and will flow gradually through the apertured plates 25 and 26 as needed, somewhat as through a grating.

In this instance, thev plate 26 has its margins fixed as by screws 21 to a downwardly projecting inner rim 28 of the reservoir 24, spacer strips 29 being inserted between the margins of the plate 26 and the rim. Me-dially, plate 25 has a depressed portion providing between itself and the spacer strips 29 a slot-like channel 30 in which the flat plate 25 is slidingly received. The plates 25 and 26 have the usual sifter apertures 3| and '32 respectively therein which in one relative position of the plates 25 and 26 register and in other relative positions are out ofregister, either completely or partially, so as to cause gradual passage therethrough of the comminuted material, when relative movements of the plates 25 and 26 occur as more particularly later described.

A cover plate 33 is indicated for the reservoir 24, the cover plate having a rotatable latch member 84 which is pivoted to the cover as at 35 and is notched as at 36 to pass about the neck 31 and under the head of a lock bolt 38 here shown screw-threaded (Fig. 2) into a boss 38 formed integral with the interior surface of the reservoir 24, a web 40 reinforcing the boss. The latch 34 for convenience may have a thumb piece 4| by which the latch may be manipulated.

It will be understood that the reservoir 2411s almost as long transversely of the machine as the appliance compartment ll, both of which it will now be understood are elongate in this direction so as to define a relatively wide path of operation for the machine in its travel. Similarly elongate within the appliance compartment II and directly beneath the reservoir 24 is a brush 42 comprising a brush board 43 and a plurality of tufts 44 of a suitable polishing bristle, arranged in rows, and in this instance, in three rows, along wax, for example, as the latter is sifted down thereinto as already referred to, and both the bed 46 of the trough and the brush board 43, in register, are perforated at spaced apart intervals 41 to cause the wax to pass therethrough and through the brush to the floor adjacent the parts of the floor upon which the brush is operating at any particular time. Turned down struck out tongues 46a, which enter the perforations 41, help to locate the brush with respect to the holder, these tongues being struck out from the trough bed 46.

The brush holder 45, in turn, is carried by a movable support therefor here shown in the form of a yoke 48 of bar stock turned out at its free ends and riveted to the in-board side of the brush holder 45 as at 49. The wall Ila of the appliance compartment l I is vertically slotted in two places as at 58 to pass the ends of the yoke 48 thereinto from the mechanism compartment 12 and to permit reciprocating movement in a horizontal plane as well as some oscillating movement in a vertical plane of the yoke and with it the brush holder and brush, as next described.

To this end the yoke 46, within the mechanism compartment, is suspended, by four parellel links it, from a sub-frame 52 carried by the frame It) within the mechanism compartment iii, the links being articulated as at 53 with the subframe and as at 54 with the yoke. The subframe is advantageously in the form of an inversely channeled plate having a flat body 55 and down-turned flanges 56 at each side, to which flanges the links 5| are pivotally attached as shown. Adjacent each side of the sub-frame the body 55 is holed and has riveted therein as at 51 the upper end of a rigid sleeve 58 in which is telescopically received a downwardly projecting guide post 59 depending from the underface of the frame H! as by being secured as at 60 into an internally threaded boss 6| on the underface of the frame.

The sub-frame 52 is thus slidaoly adjustable on the two guide posts 59 within the frame but is secured and maintained against lateral movement therein. To prevent vertical movements of the sub-frame on the guide post 58 after an adjustment of its vertical position thereon has been made and at the same time to provide means for readily making such adjustment, the subframe as best seen in Figure 3 of the drawings carries centrally thereof an upstanding king pin 62 which has screw-threaded engagement as at 63 in a bearing 64 formed integrally with the upper wall of the frame. The king pin 62 is rotatable as at 65 in the body 55 of the sub-frame and is rotatably secured thereto by a screw bolt 66, the shank 61 of which is threadedly received in a tapped bore therefor in the lower end of the king pin 62. A washer 68 interposed between the head of the screw bolt 66 and the underface of the sub-frame prevents separation of the subframe from the king pin while permitting the latter to be rotated with respect to the frame and to the sub-frame to adjust the height of the latter vertically with respect to the frame. An adjusting knob 69 at the upper end of the king pin permits ready rotation of the latter, and the lock nut 18 which screws onto the king pin and into cooperation with the bearing 64 fixes the adjustment against accidental displacement. The adjusting knob 69 and the lock nut 10 are both desirably knurled about their peripheries to facilitate manipulation when an adjustment of the height of the sub-frame, and consequently of the brush 42 with respect to the floor 22, is des sired to be made.

Further in accordance with the present invention, for operation of the brush, an electric motor II is mounted on the frame it! with its driving shaft 12 vertical in the frame, to the rear of the sub-frame 56, just forward of the rear wheel l5, and thus accommodating itself to the tapered outline of the frame at this point.

To the motor driving shaft 12 is secured a wrist block 13 from which depends an eccentric pin 14. A pitman I5 is articulated as at 16 with the eccentric pin 14 and as at 11 with a stud I8 threaded as at 19 into the horizontal part of an angular lug 8| suitably secured to the yoke 48 centrally thereof. The head of the stud I8 is desirably of sufficient size to lap the upper face of the pitman 15 so as to maintain the latter horizontal at all times and the eccentric pin I4 is downwardly elongated so that the end of the pitman encircles the latter and may slide u and down thereon Without disengagement therefrom.

during adjustment of the sub-frame 56 vertically of the frame, whereby the operating connection of the motor to the yoke 48 is maintained without interruption in various adjusted positions of the sub-frame. 4

The frame it! is shown cut away as at 82 to receive the motor II in a circular area conforming to the size and shape of the motor, and an annular flange 83 on the motor casing is secured as by screws 84 to the margins of this portion of the frame.

The machine may have the usual elongate handle common to floor devices of various kinds, and such as indicated at 85 (Fig. 5). The handle where attached to the machin ma be furcated as at 85, each furcation being articulated with the frame as by a pivot stud 01 passing through the handle furcation as at 88 and being threadedly received as at 89 in an attachment So constructed and arranged, the brush 42,

when the motor is running, will vibrate back and forth over the floor and in polishing engagement therewith, the brush making rapid short strokes within the appliance compartment II of the device, which have a rubbing or polishing action on the -floor. At the same time, the fiowable polishing material passes through the brush and to the portion of the floor upon which the brush is working. It will be observed that the brush holder 45 is suificiently wider (longitudinally of the machine) so that the wax falling from the reservoir 24 Will drop into the brush holder in all positions of the stroke of the brush. The trough-like brush holder thus acts as a sub-reservoir. Operation of the machine and consequent vibration of the frame will cause the powdered wax for example to fall through the apertured plates 25 and 26 in relatively small portions continuously as the machine operates and through the perforations 4'! in the brush. The plates 25 and 26 ma be manually adjusted to provide any suitable degree of openingof the sifting apertures 3| and 32, the plate 25 projecting for this purpose beyond the plate 26, as best seen in Figure 4, and having advantageously a finger piece 9I for manual movement of the plate.

Also as so constructed and arranged, the links 5|, from which the brush yoke is suspended, are of substantially the same length and thereby maintain the yoke and brush substantially horin zontal at all times, while by this swinging a1"- rangement the brushhas both a reciprocatory motion in a horizontal plane and a slight oscillatory motion in an arc in a vertical plane, which is to say that as the links 5| swing back and forth under the influence of the pitman they act somewhat as a pendulum and the low point of their are of movement is at the middle of each backward and forward stroke 'of the brush. This results in the brush 42 having both a lateral and a downward movement, the lowest point Of downward movement occurring in the middle of each stroke of the brush and thus enhancing the rubbing and polishing action of the brush. Since the motor operates at relatively high speed and the brush may have a short stroke of say approximately one-half an inch in each direction, this downward and lateral polishin action is rapidly repeated in a short interval of time over a given floor area and accomplishes what with a slower stroke could only be accomplished b greatly enhancing the pressure and length of the stroke.

Another advantage of the somewhat pendulumlike movement of the brush, already referred to, is that the brush in oscillating comes down on the particles of wax instead of pushing them away from it, thus'contributing to economy of wax consumption as well as enhanced results.

In addition to the structure and function already described, the machine may include, if desired, in accordance with one aspect of the present invention and as shown in Figures 3 and 4, the addition of a modification thereto, which will be next described, the parts being otherwise the same as already referred to.

As shown in Figures 3 and 4, instead of depending uporrmechanical agitation of the powdered Wax in the reservoir 24, the plate 25 may be arranged to be electrically actuated and the mechanism here shown for this purpose may be employed. Inthis instance, suspended to hang from the plate-like body 55 of the sub-frame 52 as by brackets 92, secured by screws 92a, is a solenoid device 93', the armature 94 of which'has connected thereto a hanger finger 95, the lower end of which is turned horizontally as at 96. which spans and takes under a pusher bar 91. the latter being pivoted as at 98 to the horizontal-part 99 of a lug I 00 suitably secured to the yoke 48. I

A tension coil spring IOI anchored to the yoke at one end as at I02 and to the pusher bar 91 at the-other end as at I03 normally retracts the pusher bar and with it the solenoid armature 94 when the solenoid is not energized, When however the coil of the solenoid has a current passed therethrough, by means of a suitable electric con? nection as is Well known in the art and need not be here described, the armature 94 is pulled inwardly of the solenoid, and the hanger finger 95 of the armature pulls with it, against the action of the tension spring IN, the free end of the pusher bar from the position as shown for this bar in Figure 4, in broken lines, to the position shown in full lines.

In this latter position, each time the yoke 48 and with it the brush 42 moves forwardly, the pusher bar moves with it, sliding on the horizontal part 96 of the hanger finger 95, and hits the bumper member I04 of a bell crank lever I05 which'is pivoted at I06 to the margin of the fixed sifter plate 26. The other end of the bell crank is articulated as at I01 with the movable plate 25, for this purpose passing freely through an elongate slot I08 in the fixed plate 26. The pusher member 91 thus acts as a tappet and the bumper member I04 as a tripper, for agitating the sifter plate or grating.

When the yoke 48 moves rearwardly during one-half of its cycle of movement, a tension spring I09 secured as at II 0 to the elbow of the bell crank I05 and at its other end as at III to a lug II2 carried by the under wall of the appliance compartment II, retracts the bell crank in this direction, and moves the movable plate 25 in the opposite direction to which it has been previously moved by the pusher bar 91, thus causing alternate movements in opposite directions of the sifter plate 25 with respect to the sifter plate '26 and intermittently opening and closing the sifter apertures 3| and 32 while at the same time agitating the powdered wax Within the reservoir 24 and causing delivery of the wax in limited but continuous quantities to the brush holder 45 for passage through the brush to the floor.

It will be understood that it is not necessary that this agitation by meansof the solenoid be carried on continuously during the entire operation of the machine, but generall only at inter vals, since the brush holder 45 will itself act as an intermediate reservoir for the wax, and normal agitation of the device resulting from its operation will cause some of the wax to sift through from the reservoir 24 to the floor. An electrical connection for the solenoid 93 may have in circuit therewith a spring push-button switch such as II 3 on the handle (Fig. 5). Another switch II4 of the throw type may control the circuit to the motor, the circuit to the solenoid being in parallel therewith.

- and operation shown for purposes of exemplification, and, furthermore, that the invention is capable ofembodin'ient in structures differing in degree of appropriation of one or more aspects thereof.
